IMPROVEMENT IN HOR$E-PQWERS.

Specification forming part of Letters Patent No. 1 15,4973, datedDecember 9, 1873; application filcd November 1, 1 73.

To all whom it may concern Be it known that I, DANIEL WoonnURY, of thecity of Rochester, in the county of Monroe and State of New York, haveinvented certain new and useful Improvements in Horse-Powers; and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same.

My improvement relates to mounted horse powers, and, in generalprinciple, is similar to other patents heretofore issued to me. Theinvention consists in the construction and arrangement of parts ashereinafter described.

In the drawings, Figure 1 is a plan. Fig. 2 is an elevation. Figs. 3 to15, inclusive, are detail views.

A is the main frame, attached to an axle or bolster, B, which may eitherbe mounted on wheels 0 G, as shown in Fig. 2, or on a sled, O, as shownin Fig. 13. The main frame is at tached well forward on the axle, so asto bring the preponderance of weight in front, and it is braced andstayed by straps a a, bolted on the under side of the mainframe, andencircling the body of the axle, as shown in Figs. 2 and 11. D is thetraveling frame, pivoted at b b to the under side of the main frame, orto arms thereof, just in front of the axle, instead of to thecross-piece of the main frame back of the axle, as has heretofore beendone. The pivotal point is thus so far forward that the axle can extendout full length for the attachment of the wheels, and the leveling-framecan be made much shorter than usual, not extending much.

forward of the machine itself, thus allowing the tumbling-rod to passfreely over it, instead of under it, as formerly. The leveling-frame isused as the support for the machine in trans portation, being raised forthat purpose, and resting on front wheels. E is the rim, and F thebull-wheel or main driving-gear, of the machine, which are cast in onepiece. These parts revolve upon the .main frame, and the bull-wheelgives motion to two pinions, l 1, on an inclined shaft, 0, Fig. 2, whichextends One of these pinions wheel, by which the same motion is impartedto shaft 0. A stationary pinion, 3, is located at the rear of themachine, under the pinion 1 and beneath the bull-wheel, for the purposeof balancing the gears and preserving the engagement. The teeth on theupper side of the bull-wheel are longer than those on the under side, soas to allow the proper play of the bullwhe'el and prevent anydisengagement under long wear. The journals of the pinion 3 rest'in abox, 0, Fig. 11, that is supported by a basebar, f, at the bottom. Aclamp, g, rests against the rear of the box. By this means the said boxmay be adjusted higher or lower, and clamped at any desired position,and the parts f 9 being made of wood, they will break under heavystrain, and thereby prevent injury to the gearing. This obviatesdifficulty from one cog striking upon another. G, Figs. 1 and 5, is acovering ring or cap, which fits over the bull-wheel. H H, Figs. 1 and5, are two guide blocks or slides, which rest upon the ends of the arm2' of the main frame. Each has a fork, is, which embraces the inner edgeof the bullwheel. They are made adjustable lengthwise by means of keysll, which are driven into sockets in the bar 17,- and said blocks arefixed at any position byscrews and slots m m on top. Each block H has alip, 10 which laps down over the arm 1 on the side reverse to the motionof the bull-wheel, the arrangement being such as to allow the arm i toextend all the way out.

The object of this arrangement is to keep the bull-wheel in place, bothvertically and laterally, against the strain which occurs in operation,or if the cogs slip. The blocks can be tightened to any. desired degreeby driving the keys, and the fork embracing the bullwheel prevents anyescape of the latter, although allowing it a free revolving motion.

I is one of the sweeps by which the power is applied. Four or five aregenerally used. K is a brace-arm, pivoted to the sweep at a, and restingat the inner end against a bearing, 0, secured to the rim of thebull-wheel. The end of the brace-arm is made angular or rounded, to fitthe angular or rounded space between the bearing and the rim, and it isprovided with an iron shoe to prevent injury and insure proper strength.A shank, p, rests in a socket of the brace-arm, having a longitudinalplay, Fig. 6, and the end of the shank is provided with a hook, q,

purpose of a fulcrum.

that engages with an eye, 1*, on the under side of the bearing 0. Thisarrangement allows the engaging of the hook and eye, and the proper playof the shank p, in straightening the brace-arm back to engage with thesweep. When the pressure of the sweep is applied against the brace-arm,the strainis all expended on its end resting against the bearing, andnone comes on the hook and eye, the latter being employed only forconnecting and holding the parts in place, and holding it in place whenthe strain is reversed, or the horses hold back. J L are outrigs orstake-bars, attached to the sides of the machine and staked to theground, to resist the strain and keep the machine in place. Their innerends have sockets, which fit upon bearings s s on the front and rear ofthe main frame. Their outer ends meet at an angle, and are securedtogether by a socket, t, of the part L, which fits upon a horn, a, ofthe bar J. The outer end of the bar J has a staking-socket, '27. M is astandard, and N a share or stay-bar. The standard is attached at thebottom to a cross-piece of the leveling-frame, and its top extends upthrough a slotted plate, 20, which rests on top of the supporting-bars00 a; of the main frame. The share is made to rest on the ground, andpasses up through a similar plate, 2. The standard and share are bothprovided with a series of holes, a a, through which pass pins restingunder the plates to hold up the main frame. The standard is employed forsustaining the main frame while the leveling-frame rests upon the groundin operation. The share is employed for sustaining the main frame whilethe leveling-frame is being elevated for the purposes of transportation,or to let the main frame down upon the leveling-frame. In such case theshare is fixed in position, and the standard released, and theleveling-frame can then be raised. WVhen a sled is used, the share may,in some instances, rest upon the front cross-bar of the sled, and

hold up the leveling-frame at such a height as not to interfere with thetongue of the sled. O is a reach, consisting of a straight bar with lugsb N, and a cross-piece, 0 at the rear. In Fig. 3 it is shown attached tothe end of the leveling-frame by means of a pin, (1 with the cross-piece0 resting on top, and serving the In this condition the, reach serves toattach the front end of the ma chine to the front or rear axle of acommon wagon, or to the wagon itself, for transportation, in such casebringing the leveling-frame up sufficiently to run clear ofobstructions,but allow the gears to run low. hen the machine is mounted on a sled,the reach may be reversed, as in Fig. 4, and stand upward, forming afoot-board. The driver sits upon a seat, 1, attached to a cross-bar, fwhich is sustained by standards g which fit on the bearings 0 0. Thecrossbar f, in connection with another cross -bar, 11 on the rear of themachine, serves as the support for the levers when detached fortransportation. The reach may also be used beneath the machine, beingscrewed or otherwise secured to the under side of the axle, its rear endprojecting back, and the cross-piece 0 resting on the ground, while thefront end projects forward, and is connected to the hook 7L2 of theshare, the latter being drawn up tight and secured by the pin to theplate 2. The reach, in this case, serves to give a broader bearingbeneath the machine, and a support back ofthe axle, to obviate tipping,as the power is applied on different sides of the machine.

Q, Figs. 1 and 12, is afriction-brake, hingedor otherwise attached at ito the main frame, in position to receive the foot of the operator. Ithas a curved bearing, k which extends downward at right angles, ornearly so, and rests against the inner periphery of the rim of thespur-gear 2, or against any other part of said gear. A spring, 8 restsunder said brake, so as to remove the contact when it is not in use. Bypressing upon the long arm of the brake, the operator can check themotion at any time. It R are the boxes in which the shaft 0 runs. Theyare made convex or rounding on the four sides, so as to adapt themselvesto the position of the shaft at all times, and prevent binding orstrain,

which would occur if they were straight-sided and fitted closely inplace. The cap P, which fits over the rear box, rests loosely, so as notto bind the box. The outer ends are provided with cylindricalprojections m Fig. 9, which fit into corresponding sockets of thepinions 1 1. B y this means the boxes are made longer, so that an equalbearing comes on both ends, and undue binding and strain are avoided,and the shaft can be made stronger. This also insures more even wear onthe ends of the boxes. The boxes are made in two parts, a 0 the first,preferably, of metal and babbitted, and the last, preferably, of wood,fittin into the other, as shown in Fig. 10, which is an end view. Theopening in the part a is large enough for the shaft to be insertedlaterally, and the part 0 closes the space around the shaft. The part 02receives the great wear, while the part 0 allows the pinion to be takenoff or replaced, and facilitates the keying of the pinion and theremoving the same for repairs. It also .makes the box stronger. At theinner end the parts may be secured together by a vertical pin. 12 is anoilgroove. S is a Windlass, mounted in bearings on top of the mainframe, and employed for drawing up loads of any kind. A shifting-clutchmay be connected with its shaft and arranged to shift the motion byreversing a lever or otherwise. At the outer end of the shaft is aspur-gear, 4, which engages with the bull-wheel, and transfers motion tothe windlass. The clutch may be so arranged as to allow the gear 4 torun loose when not desired to give motion to the windlass. A is a hangerhinged on the under side of the main frame, supporting a pulley, m Thewinding rope from the Windlass passes down around the pulley, and thenceextends to the load to he moved. To a bail at the lower end of thehanger is attached a stay-cord, o staked to the ground. This hanger andpulley can be turned up against the frame to be out of the way intransportation, and, being hinged, it will yield so as to prevent twistupon the frame. T is one of the couplings of the tumbling-rod. Theshafts have the ordinary forks g (1 that of one part being made of lessdiameter than the other. They are secured by the ordinary cross-pins 11' and an encircling ring or shield, 2 surrounds the whole. One end ofeach pin fits in a socket bored through one side of the ring, andpartially through the other side, and when in place the end of the pinresting in the open end of the socket is covered by a cap, t which isfastened in place in any desired manner.

The arrangement above described is a convenient and cheap means ofsecuring the pins, and is also such that the ends of the forks of therods cannot wear together, which is a great difliculty in the old styleof coupling. The ends always remain clear of each other under alldegrees of wear.

U is a jack for transferring motion from the power.v It consists of aframe, V, staked to the ground at a distance beyond the path of thehorses. In this is pivoted, at j, a block, \V, and to this block ispivoted, by a bolt and nut, a a standard, X. The pivots of the parts Wand X are at right angles to each other. The tu mblin g-rod passesthrough suitable bearings in the standard X, and has a bevel-gear, 6,upon its outer end. Into this gear meshes a bevel-pinion, 5, on a shaft,0 which extends vertically through bearings of the standard. On theupper end of the shaft is a band-pulley, 3 Beneath the pulley is a ring,Z, which turns freely upon a suitable seat at the upper end of thestandard. The ring is held in any given position by a clamp, 10tightened by a set-screw. On one side of the, ring is afixed bearing, Jwhich holds a loose pulley, a. The band, as it comes onto the mainpulley Y, passes over the small pulley (1. which acts as a guide to keepthe band in place, and the small pulley can be turned to any position bythe -adjustment of the ring-Z, as before described, thereby allowing theband to run in any direction. is a segment-guide, pivoted at the lowerend to a plate, b that has a series of holes, as shown in Fig. 2. Theupper end of the segment passes through a slot in the standard X, andthe latter is held to it at any position by a set-screw, e

By the arrangement above described, the standard X, with its pulleys Ya, can be turned to any incline, either upon the joints 7 or 10 andthese two adjustments are at right angles to each other. The position isfixed at any adjustment by the nut a and set-screw c, as beforedescribed. The plate b allows the adjustment on the pivot 20 to takeplace by changing the pivot of the end of the segment to different holesin the said plate.

When the machine is mounted on a sled, I

make the front cross-piece of the sled removable from its sockets, toallow the tumblingrod to pass down in the proper direction.

Having thus described my invention, what I claim as new is- 1. In amounted horse-power, such as shown and described, the leveling-frame D,Windlass S, outrigs J L, slides H H, and brake Q, combined with the mainframe A, to operate in the manner and for the purpose specified.
